Utah and southwest Wyoming.
.DAY ONE...Tonight
Snow will begin across the northern outlook area late tonight.
.DAYS TWO THROUGH SEVEN...Sunday through Friday
Widespread heavy snow and much colder temperatures will spread
across the outlook area from north to south on Sunday. The cold
front could bring near whiteout conditions to the mountain passes
in heavy snow and strong winds for a few hours as it moves south
on Sunday.
The snow will slowly taper off from the north Sunday night
through Monday afternoon but will last in some areas through
Monday evening. The snow could continue into Tuesday across
mountainous locations favored in northwest flow, as well as
locations downwind of the Great Salt Lake and Utah lake.
Strong south winds are expected ahead of this storm on Sunday
across central and southern Utah.
The very cold temperatures that spread into the outlook area
Sunday through Sunday night will continue through Tuesday night
into Wednesday. At this time it looks like Wednesday morning will
be the coldest in this stretch with lows ranging from the low
teens to below zero. Any plants or trees that have starting
budding out will be affected by this cold snap.
